actionmailer_host_autoset

It is difficult to generate URLs with ActionMailer. Although you can
generate absolute paths from your routes, you usually need to generate
full URLs for the links in the email to be useful to your recipients.

This plugin sets the default_url_options for host, port and protocol by
providing an around_filter which will grab the values from the request
object. In the cases when the request object is not available, for example,
when running tests, default values are set instead.

This is basically a repackaging of retardase_inhibitor (github.com/luke0x/retardase_inhibitor),
with more descriptive name and a gemspec that will actually build on
github (yay for jeweler!).

Usage

I prefer to add it just around the actions when I know an Observer will
kick off an ActionMailer notifier. For example, I have an the filter kick
off in my SessionsController#create when I process a user signup.
